摘要

蟑螂与威胁人类健康的人类环境有关。2015年8月至2016年3月，对伊朗洛雷斯坦省Khorramabad的医院、餐厅和家庭环境中的蟑螂真菌污染进行了横断面研究。每月从随机选择的地点统一取样。使用标准方法从蟑螂的外表面分离出真菌。美洲大蠊（66.7%）是最常见的蟑螂，德国小蠊（18.6%）和东方大蠊（14.7%1月（30.0%）和3月（7.0%），11月（73.3%）和3月份（14.3%）蟑螂真菌污染最高和最低。德国小蠊（60.7%）是真菌污染最严重的蟑螂。念珠菌属、毛霉菌属和青霉属是蟑螂最常见的真菌污染属。统计分析显示，蟑螂侵扰地点（P=0.022）、地点（P=0.03）和每月（P=0.001）蟑螂真菌污染之间分别存在显著差异。因此，蟑螂真菌污染最高的是德国小蠊，其次是美洲大蠊和东方小蠊。在受真菌污染的蟑螂中也发现了一些人类真菌机会性病原体。最近的流行病学调查显示，感染性疾病的死亡率增加，表明蟑螂参与了它们的转移。

Comparison of cockroach fungal contamination in the clinical and non-clinical environments from Iran

Cockroaches have been associated with human environments threatening human health. A cross-sectional study about cockroach fungal contamination in the hospital, restaurant and household environments from Khorramabad, Lorestan province of Iran between August 2015 and March 2016 was done. Sampling was uniformly carried out monthly from the randomly selected sites. Fungi were isolated from the external surfaces of cockroaches using standard method. Periplaneta americana (66.7%) was found the most infested cockroach, less percentage were observed in Blattella germanica (18.6%) and Blatta orientalis (14.7%). Hospitals (66.7%) were found the most infested places in comparison with households (18.6%) and restaurants (14.7%). Households (64.3%) were found the most cockroach fungal contaminated places than hospitals (49.0%) and restaurants (59.1%). The highest and the lowest infestation of cockroaches were observed in January (30.0%) and March (7.0%) respectively, while the highest and the lowest cockroach fungal contamination were observed in November (73.3%) and March (14.3%). B. germanica (60.7%) was the most fungal contaminated cockroach. Candida , Geotrichum and Penicillium were the most frequent cockroach fungal contaminating genera. Statistical analysis revealed significant differences between cockroach infestation places (P=0.022), locality (P=0.03), and monthly (P=0.0001) cockroach fungal contamination, respectively. As a conclusion, the highest cockroach fungal contamination was observed in B. germanica, followed by P. americana and B. orientalis. Some human fungal opportunistic pathogens were also found among the fungal contaminated cockroaches. Recent epidemiological survey showed that the mortality rates of the infective diseases were increased, indicating cockroaches involved in their transferring.

期刊介绍： The Journal of Entomological and Acarological Research (JEAR), formerly the Bollettino di Zoologia Agraria e di Bachicoltura of the Institute of Entomology of the Università degli Studi, Milano, was founded in 1928 by Remo Grandori. Thereafter, Minos Martelli and Luciano Süss hold the direction of the Journal until December 2011. In January 2012 the Editor decided for the new open-access on-line version of JEAR. The Journal publishes original research papers concerning Arthopods, but reviews, editorials, technical reports, brief notes, conference proceeding, letters to the Editor, book reviews are also welcome. JEAR has four main areas of interest: -Entomology (systematics; morphology; biology; biotechnology; agriculture, ornamental and forest entomology; applied entomology; integrated pest management; biological control; apiculture and apidology; medical, urban and veterinary entomology; etc.) -Stored product pests (biology; integrated pest management; etc.) -Insect Ecology (behaviour; biodiversity; taxonomy; plant insect interaction and ecosystems; biological control; alien species; etc.) -Acarology (systematics; morphology; biology; parasitology; control; etc.) The publication of manuscripts is subject to the approval of the Section Editor who has knowledge of the field discussed in the manuscript in accordance with the principles of Peer Review; referees will be selected from the Editorial Board or among qualified scientists of the international scientific community. Articles must be written in English and must adhere to the guidelines and details contained in the Instructions to Authors.
